method_dmax: Dmax

In lactater: Tools for Analyzing Lactate Thresholds

Dmax

Description

It applies the Dmax methods: "Dmax", "ModDmax", "Exp-Dmax", "Log-Poly-ModDmax", and "Log-Exp-ModDmax".

Usage

method_dmax(data_prepared, sport, loglog_restrainer = 1, plot)

Arguments

data_prepared	The data retrieved from prepare_data().
sport	The sport at which the incremental test was performed. One of cycling, running, or swimming.
loglog_restrainer	A scalar from 0 to 1 indicating the percentage of the data that you would like to restrain for fitting the Log-Log method - This is going to be used in the Log-Poly-ModDmax and Log-Exp-ModDmax methods only. For example, 1 means no restriction (fits using the whole data), and 0.5 means that only the first 50% of the data will be used. Default to 1.
plot	A boolean to indicate whether to generate a plot from each one of the methods. Fit The method_dmax() function does not have a fit argument because all the Dmax methods have their own default fitting methods: Dmax = 3rd degree polynomial ModDmax = 3rd degree polynomial Exp-Dmax = exponential Log-Poly-ModDmax = 3rd degree polynomial Log-Exp-ModDmax = exponential

Value

a tibble with the following columns:

method	the method used to estimate the lactate threshold
fitting	the fitting method used to predict the lactate curve
intensity	the intensity associated with the estimated lactate threshold
lactate	the lactate concentration associated with the estimated lactate threshold
heart_rate	the heart rate associated with the estimated lactate threshold
plot	the plot produced to display the lactate threshold
